This Regulation is the Electricity Supply (Corrosion Protection) Regulation 2008.
This Regulation commences on 1 September 2008.Note. This Regulation replaces the Electricity Safety (Corrosion Protection) Regulation 2003 which is repealed on 1 September 2008 by section 10 (2) of the Subordinate Legislation Act 1989.
(1) In this Regulation:approval means an approval in force under Part 2.
approved system means a corrosion protection system the subject of an approval.
Director-General’s guidelines means the guidelines for the time being approved by the Director-General under clause 13.
foreign structure, in relation to a corrosion protection system, means any metallic structure (other than the primary structure for that system) that is situated in the vicinity of the system, whether in or on the ground or in or on water.
interference test means an electrical test that indicates the risk of corrosion to a foreign structure by a corrosion protection system.
primary structure, in relation to a corrosion protection system, means the structure that the corrosion protection system is installed to protect.
the Act means the Electricity Supply Act 1995.
(2) A person is taken to operate a corrosion protection system for the purposes of this Regulation if:(a) the person has control over a corrosion protection system that has been installed to protect a structure, and(b) current flows between the system and the structure.(3) Notes in this Regulation do not form part of this Regulation.
(1) This Regulation does not apply to:(a) a galvanic anode system that has been installed to protect:(i) a compact structure, but only so long as the maximum current flowing through the system does not exceed 150 milliamperes, or(ii) any other primary structure, but only so long as the maximum current flowing through the system does not exceed 150 milliamperes for each 500 metres of the length of the structure along its greatest dimension, or(b) any corrosion protection system that has been installed to protect:(i) the internal surface of a water storage tank, reservoir or other similar structure for storing water where the structure isolates the system current from the external environment, or(ii) marine vessels that are not permanently moored.(2) This Regulation applies to all other corrosion protection systems.(3) In this clause:compact structure means a structure (such as a storage tank) the greatest dimension of which, being a dimension of height, length or breadth, is no greater than 5 times the size of the smallest of those dimensions.
galvanic anode system means a corrosion protection system that operates by means of an electrochemical reaction in which a metallic anode corrodes.
